Question

A Rolling ball has which of the following type(s) of motion :

• A. Only rotatory
• B. Only translatory
• C. Rotatory and translatory
• D. Neither Rotatory nor translatory

Answer 1

The correct option is C

Rotatory and translatory

Since the rolling ball is travelling in a straight line as well as rotating at the same time.

So, it has rotatory and translatory motion.

Rotatory motion means moving around w.r.t a fixed axis.

Translatory motion(rectilinear motion) means moving in a straight line.
